The Communist Party Unit Committee in the southern province of Long An have ordered a fresh investigation into two officials' involvement in a party at which a woman drowned last month, Tuoi Tre reported.

According to Thai Van O, deputy secretary of Can Giuoc District's Party Unit, the new investigation ordered Thursday has nothing to do with police's investigation into the death of Dinh Thi Kim Phuong.

Instead, its findings will be the basis for them to decide punishments for Nguyen Kim Doan, chief of Can Giuoc's People's Procuracy and his subordinate Nguyen Huong Giang, O said.

On August 20, Doan and Giang joined a drinking party on a barge along the Vam Co River together with a dozen other people, including five women.

After drinking, some of the party goers went swimming in the river. Phuong, who didn't join them because she couldn't swim, fell into the river accidentally, police said.

Following police's initial findings, Can Giuoc's Party Unit committee disciplined the two officials by asking to review their actions.
